T0 all fur/'tom it may concern Be it known that I, FRANK J. Gines, a citizen of the United States, residing at Tyrone`r in the county of Blair and State of Pennsylvania, have invented a new kand uscful Auxiliary-Tire Attachment, of which the following iS a Specification.

The invent-ion relates to an a uXiliury tire attachment for pneumatic tires.

The object of the present invention is to provide for pneumatically tired wheels a simple, inexpensive and efficient auxiliary tire, adapted to bek rradily mounted on an ordinary pneumatic tire. and capable ol" coinpletely protectingr the Same and ot reliemruid a. pneumatic tire of pnnctures and all other troubles resulting from direct Contact ot the tire with the surfaces of the roiulv-fays.

A further object ot' the invention is to provide a device oli' thi,` character equipped With an outer solid resilient tire, arranged to receive the wear and tear and adapted lo contribute to the cushioningr action ot' the wheel.

lilith these and other objects in view. the invention consists in the construction and novel combination ot' parte hereinafter fullv described. illustrated in the attr-ompanlvingf drawing. and pointed out in the -t-laim# herrto apiliended; it being* understood that v ous changes in the form, proportiim` si fc and minor details, ol' wnstriwtion. within tho scopo of the claims, may be rosortrd to without departing from the spirit or sacrilic ingr any ot the advantagrjw; ole the invenliioi'x.

ln the drawingsy :-i"ihluro l a side elcvation oi a portion of i pnemnativallv tired wheel provided with an auxiliar)1 tire and rim, constructed in accordance with this in vcntion. Fig. 2 is' au enlarged longitudinal sectional view of a portion ot' the Same. Fig. 3 is a transverse sertional view on thi line 3 3 of Fig. Figy =l is a detail sectional perspective view of a portion of thtl auxiliary rim.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

ln the accompanying drawing in which is illustra-ted the preferred embodiment of the invention, 1 designates a wheel, designed for use on automobiles and various other motor vehicles, and provided with a pneumatic tire 2 and equipped with an auiiiliarjr lim und an auxiliary Solid rubber tire il. The pneu- Vmatic tire may be 0f any preferred type, and

its outer tread portion lite within an inner annular channel l ot' the auxiliary riim which if; also priwided with an outer annular channel 5 `lor the rcreption ot the solid resilient tire 3.

The auxiliary rim comprieee in ite eonstructure spaced annular eide plates or niemlicni G and 7 and telescopic cylindrical tlanges or members S and 9. formed integral, respeo tively, with the` side plates or members G and 7 and extending inwardly from the same at points4 intermediateofthe inner and. outer it .ot the ii platesorucnilicrs. a rlourly illu rated in Vig". l of the ilraivingg.

The auxiliar rim all'ordsl complete protectior i'or pneumatic tirey 'without interfering with tue cushioning action thereof, and the rr'\li!-.uiy oA the wheel is incrcaswl uy the solid ruiu'r outer tiro. The :solid ruhlur outer tire, which receives. ali the wear and tif-n', may he rcaflilv rrplarod at a comparativelv low cos The r- \'linilrical telescopic llan'f' u wenn here which lit snugly one within torni a two-part circuinferf-ntial "gf weh and they may lie easily ai quickly placed on the pneumatic tire.

The openings ll a vcreol",y alinod. and the grof which are loratod at tlu` or 3 when the parts are auf form inner and outer proie-1 embedded iu the treuil ol' tin- .f smania tiro and the inner tace oi' the sfila outer tire. whereby the latter and the fiumi? :rv rim are prevented trom creeping circumfereiitially around the Wheel. This is an advantage as the inner portions of the side plates may be terminated at opposite sides of the outer portion of the pneumatic tire and it obv1atcs the necessity o." eXtending the side plates to the rim or felly of the wheel. The bolts are equipped with nuts 15, but any other suitable fastening devices may be employed.

What is claimed is zl. The combination with a pneiiunatic tire, and an outer solid tire arranged in spaced relation, ot' an auxiliary rim provided with inner and outer channels receiving the said tiros and composed of annulaiside members, and cylindrical telescoping flanges or members extending from the inner faces of the side members at points intermediate of the inner and outer edges thereof and provided with registering transverse bends forming grooves and providing inner and outer proiections, which are embedded in the Said tires to prevent the rim and the outer tire from creeping, and fastening devices piercing the side members and arranged in the registering grooves and securing the parts together, said fastening devices passing be tween the fvuter and pneumatic tires Without piercing either of them.

The combination with a. pneumatic tire, and an outer solid tire spaced from the pneumatie tire, of an auxiliary rim composed of annular spaced side lates, an annular flange formed integral Wit i one of the side plates and extending across the space to the other side plate and forming inner and outer channels which receive the said tires. said annular flange having transverse bends which are embedded in the solid tire to prevent creeping, said plates having openings in. alinement with the said bends, and fastening bolts passed through the openings of the side plates Within the said bends and securing the parts together.

In testimony, that I claim the foregoing as my own, I have hereto aliXed my signature in the presence of two Witnesses.
